A: blacks in Montgomery boycotted the public bus system
It is always hard to say what the "initial" cause is- the initial cause
is always caused by something else. I'd say in this case that the
initial cause was the positioning of Soviet nuclean weapons on Cuba,
which was a very tangeable threat to the US. The noticing of these
weapons by the US marked the start of the Crisis.
But you should
also see the positioning of the weapons on Cuba in a wider context of
the Cold war. Specifically, Cuba felt threatened due to the Bay of Pigs
Invasion in 1961 ( a year earlier) and this caused Cuba to invite
Soviet weapons as a protection.
Answer:
Clause 18 from Article 1 Section 8
Explanation:
Clause 18 from Article 1 Section 8 granted the power to the government make all Laws which shall be necessary to carried out their main duties that is directly written on the constitution.
This single clause alone, granted so much flexibility for the government to create agencies and regulations that are not directly written/regulated for them within the constitution.
Example of the usage of this would be the creation The First and Second Banks of the United States, They does not necessarily written on the Constitution, but the government use it to control and regulate the economy of the nation as a whole.
